    摘要: A method of forming a buried oxide/crystalline III-V semiconductor dielectric stack is presented. The method includes providing a substrate and forming a layered structure on the substrate comprising of layers of different materials, one of the different materials is selected to be an oxidizable material to form one or more buried low index oxide layers. A first sequence of oxidizing steps are performed on the layered structure by exposing the edges of the layered structure to a succession of temperature increases in the presence of steam from an initial temperature to the desired oxidation temperature for a time interval equal to the sum of the time intervals of the succession of temperature increases. Also, the method includes performing a second sequential oxidizing step with steam on the layered structure at the specific oxidation temperature for a specific time interval. Furthermore, the method includes performing a final sequence of oxidizing steps on the structure by ramping down from the desired oxidation temperature to a final temperature when the oxidizing material is completely oxidized to form the one or more buried low index oxide layers.
